In recent intense price fluctuations of Bitcoin and Ethereum, the interest of cryptocurrency traders has surged, leading to a rapid increase in the open contract volume of these two major crypto assets. The open contract volume of Ethereum broke through 70 billion USD for the first time at the end of August, setting a historical high; meanwhile, the open contract volume of Bitcoin remained at a high level of 80 billion USD. Historical data shows that after the open contract volume reaches a historical high, there is usually a period of consolidation, followed by a trend of simultaneous rise in price and open contract volume. This suggests that if the open contract volume sets a new record again, the prices of Bitcoin and Ethereum may also reach new records.
